Claim support
At the heart of BASF’s strength as a chemical industry leader is our expertise in science and dedication to sound scientific processes. BASF Personal Care leverages these qualities to deliver ingredients with verifiable properties based on science excellence – and we are committed to backing each performance claim with full support for our customers.
That means we can give you detailed results from standard testing and innovative methods to reliably demonstrate product benefits.
Exemplary Test Methods
Bending Stiffness (BS)
The Bending Stiffness describes the stiffness of styling formulations using a force value [ cN ]. Maximum force at breakage of standard hair strands is measured.
Curl Retention
The Curl Retention value describes the humidity resistance of styling formulations using a percentage scale. Hold of standard hair curls is evaluated after 5h and 24h.
Anti-Hair Breakage Test
The amount of broken hair fibres and fibres with split ends can be determined quantitatively.
Tensile Strength
The physical strength of hair fibres is measured by determining the forces required to elongate and break them.
Autosampler DSC
DSC measures the denaturation (break-down) temperature of human hair proteins, which is a precise indicator of hair damage.
Pillow Talk
Trained panelists match the skin feel with different textile surfaces of pillows after applying a skin care formulation on the volar forearm.
Hair Conditioning & Shampoo
Optical Microscopy
A digital microscope allows to easily observe the surface of hair fibres to obtain information on the degree of damage of human hair.
Hair Styling
Elasticity
Flexibility and Elasticity is determined by measuring the deflection forces of horizontally clamped standard hair strands. Evaluation of maximum force and differential force after 10 repetitions.
Skin Care
Transepidermal Water Loss
Transepidermal water loss (TEWL) is a measurement of the amount of water emitted from the body to the outside via the skin; skin barrier damage is indicated by an increase in TEWL.
Skin Care
Corneometer
Corneometry is used to measure the skin surface hydration; it is based on measuring the changes in electrical properties of the skin due to moisture content.
